④ power status The real-time power supply voltage and current of the device are shown. Due tothe update of the algorithm, the data accuracy continues to indicate that there willbe some differences in different versions of different versions, which is a normalphenomenon. Mainly through the power supply voltage to help the after-salespower supply troubleshooting.
⑤ communication status "Communication status" indicates the communication between the touch screenand the motherboard. If not synchronized, check the screen cable. "Anti-shake" is used to deal with poor contact with safe locks, which range from0 to 300 ms. Click "Device authorization box" to set the parameter range on thepassword page as shown in Figure 3.9. The password is "ffffffaa300" where "ffffffaa"indicates the lock anti-shake parameter and cannot be changed. "300" means 300ms. The effect is that when the trigger signal is normal and the disconnection time of thesafety lock signal is <300ms. Material welding used to deal with poor surfaceproperties and unstable conductivity (e. g. rust) is usually set to 0.
Figure 3.1-10 Monitoring page-auxiliary status bar-ground lock anti-shake password"Motor driver temperature" and "protective mirror temperature" indicate themeasured real-time temperature of the two parts. "Motor driver temperature" affects the motor swing performance of the environment. If the environment is poor,it will lead to the abnormal temperature increase, affect the laser scanning speed, and then lead to the decrease of weld quality. The lens temperature reflects theworking state of the lens to help determine whether the lens is damaged.
